Just bought a 2005 S60 2.5T AWD a couple months ago and have noticed that the front end is making squeaking/light clunking sounds. The car has approximately 55,000 kms (35,000 miles). This problem didn't start until I replaced all four tires. The dealership performed a wheel alignment and balancing when the new tires were installed. After the new tires were installed I noticed a light clunking sound/squeaking noise when travelling at low speed over bumps, especially when it is hot outside (over 30C)or in stop and go traffic. The problem doesn't seem to occur outside of these conditions. I tried listening to the sound with the windows down, but I couoldn't hear anything outside the vehicle. I brought the vehcile to the Volvo dealership and they replaced the front bearing shock absorbers (both), the shock absorbers, and the spring seats under warranty. The problem continues to persist, but more intermittently than before the warranty work. I returned the car to the dealer, where they inspected it said that there was nothing wrong with it. Any suggestions?

 

You might need new swaybar end links or tierod ends.
